What is the orbital velocity of the Moon?
1.022
Orbital parameters (for orbit about the Earth)
| Moon | |
|---|---|
| Revolution period (days) | 27.3217 |
| Synodic period (days) | 29.53 |
| Mean orbital velocity (km/s) | 1.022 |
| Max. orbital velocity (km/s) | 1.082 |
What is the atmospheric pressure of the Moon?
The pressure of this small mass is around 3×10−15 atm (0.3 nPa), varying throughout the day, and in total mass less than 10 metric tonnes.
What is the speed of the Moon?
The moon orbits the Earth at an average speed of 2,300 miles an hour (3,700 kilometers an hour). The moon’s gravitational pull on the Earth is the main cause of the rise and fall of ocean tides.
How many cubic miles is the Moon?
The Moon has a radius of 1,079 miles and a volume is 5.2 billion cubic miles, which makes the Moon about 27.3% the size of the Earth.
Can the moon rotate?
The moon does rotate on its axis. One rotation takes nearly as much time as one revolution around Earth. Over time it has slowed down because of the effect of Earth’s gravity. Astronomers call this a “tidally locked” state because it will now remain at this speed.
Is there gravity on moon?
1.62 m/s²
Moon/Gravity
What is the temperature on the moon?
260 degrees Fahrenheit
When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).
How does the attraction of the moon affect the Earth?
As a result, the slightly greater attraction that the Moon has for the side of Earth closest to the Moon, as compared to the part of the Earth opposite the Moon, results in tidal forces. Tidal forces affect both the Earth’s crust and oceans.
How often does the Moon move around the Earth?
Now the moon goes around the earth once every 29 days (approximately). At new moon, the moon and the sun are on the same side of Earth. We see the part of the moon that is in shadow, so the moon is dark. Then the moon moves around in its orbit.
Why is the moon called the Moon in our Solar System?
The Moon was likely formed after a Mars-sized body collided with Earth. Our moon is the fifth largest of the 190+ moons orbiting planets in our solar system. Earth’s only natural satellite is simply called “the Moon” because people didn’t know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610.
How are the Sun and the Moon related at New Moon?
At new moon, the moon and the sun are on the same side of Earth. We see the part of the moon that is in shadow, so the moon is dark. Then the moon moves around in its orbit. At first quarter, it has gone one-fourth of the way around Earth. Now we can see part of the moon that is sunlit, but part still in shadow.
